Many questions on this site ask how to add a footer to the Oslo master page, and it is advised to change the contents of the DeltaPlaceHolderFooter tag.
However, on my site, the Designer is activated, which means that I may only edit the .html file, not the .master file.
Therefore, the footer looks like this :
<!--SPM:<SharePoint:AjaxDelta id="DeltaPlaceHolderFooter" BlockElement="true" runat="server">-->
<!--SPM:<SharePoint:DelegateControl runat="server" ControlId="PageFooter" AllowMultipleControls="false"/>-->
<!--SPM:</SharePoint:AjaxDelta>-->
What is the proper syntax to replace the PageFooter server control with a simple div of my making?
This page explains the syntax of everything (designer snippets and whatnot) except the one thing I need: "normal", plain HTML: https://github.com/SharePoint/sp-dev-docs/blob/master/docs/general-development/how-to-convert-an-html-file-into-a-master-page-in-sharepoint.md
